Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate Chemical Properties,Usage,Production
Applications
Light Stabilizer 770 is recommended to be used in polypropylene, impact modified PP (TPO), EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA, polyurethanes, and is also effective in polyamides and polyacetals.
Applications
Light Stabilizer 770 (Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate) is a low molecular weight hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. The benefit of using Light Stabilizer 770 is the high light-stabilizing performance, particularly in PP thick sections to protect the surface. It has broad compatibility and can be easily dispersed. Compared to UV absorbers, the effectiveness of HALS, like Light Stabilizer 770, is not dependent on the polymer’s thickness. For this reason, the use of Light Stabilizer 770 also provides good light stability in articles with higher specific surface, e. g., films and tapes.
Guidelines for use
The recommended concentrations range between 0.1 % and 1.0 %, depending on the substrate, processing conditions and application. The optimum level is substrate and application specific. Extensive performance data of Light Stabilizer 770 in various substrates and for various applications is available upon request.
Physical properties
Handling
In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Avoid continuous or repetitive breathing of dust. Use only with adequate ventilation. Avoid contact with eyes. Avoid release to the environment. Avoid dust formation and ignition sources.
Chemical Properties
White solid
Uses
T770 (Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate) can be used as a hindered amine UV stabilizer in plastic materials. It can be used in the manufacturing and packaging of pharmaceutical products. Titanium oxide(TiO2)/T770 may be used in amine induced light stabilizers in the synthesis of recyclable water-based polyurethane with poly(oxytetramethylene)glycol (PTMG).
General Description
Bis(2,2,6,6-tetramethyl-4-piperidyl) (T770) sebacate is a low molecular weight ultra violet (UV) hindered amine light stabilizer (HALS) made up of nitroxyl radicals. It acts as a heat controller that can react with phenolic antioxidants incorporated in polymers.

Not classified
Biological Activity
Bis(2,2,6,6-tetramethyl-4-piperidyl) sebacate(BTMPS; Tinuvin 770) is a sterically hindered amine light and radiation stabilizer produced by Ciba-Geigy, widely used in plastics, that inhibits nicotinic acetylcholine receptors expressed in Xenopus oocytes in a use-dependent manner. BTMPS is a symmetrical conjugate of methylated piperidines that are potent inhibitors on their own, but the kinetics of inhibition and recovery are faster than BTMPS. For neuronal nicotinic receptor subunit combinations, the time constant for recovery from inhibition by BTMPS is approximately 1 to 4 h. Muscle-type receptors (α 1-, β 1-γ, and δ subunits) are also inhibited by BTMPS, but control responses are fully restored after a 5 min washout. Hybrids of muscle and neuronal subunits containing neuronal β subunits (α 1-, β 2-, γ, and δ and α-1-, β 4-, and γ-δ) blocked in a more irreversible manner than normal muscle-type receptors, suggesting an interaction between BTMPS and neuronal acetylcholine receptor β subunits. Glutamate receptors were not inhibited by BTMPS. Exposure to agonist solutions from certain plastic syringes that release BTMPS also resulted in a use-dependent inhibition of nicotinic receptors.[1]
